The kids were asleep, and I could hear a muted, distant moaning coming from our bedroom. It reminded me of labor pains, but there were three things making labor unlikely: my wife’s IUD, the absence of a gravid abdomen and the kind of unintentional celibacy that occurs between working parents raising two toddlers. I tried to ignore the moaning. In part, because it was a Sunday night, and the sound …
Pediatric physeal fractures have traditionally been described by the five-part Salter-Harris classification system.
Type I fractures occur through the growth plate. These injuries may present with normal radiographs, and the diagnosis is often made clinically when tenderness is palpated over the growth plate.
Type II fractures occur through the growth plate and metaphysis. Type II injuries are the most common physeal fractures.
Type III fractures occur through the …
Clostridium difficile is a gram-positive anaerobic bacillus which secretes toxins (A and B) that cause diarrhea and pseudomembranous colitis. C. difficile is the most common infectious cause of nosocomial diarrhea. Transmission of C. difficile can occur from contact with contaminated humans and fomites. The organism contains endospores that can survive the acidity of the stomach and reach the large intestine.
C. difficile colonizes the intestinal tract after the normal …
Pulmonary hypertension (PH) refers to increased pressure in the pulmonary circulation. It develops when pulmonary vessels become constricted and/or obstructed, which can occur in a wide variety of conditions. The increase in pressure is measured by right catheterization, and is defined as a mean pulmonary arterial pressure ≥ 25 mm Hg at rest.
PH leads to right ventricular hypertrophy and enlargement as the …

A 64-year-old man is evaluated for his quarterly diabetes care follow-up visit. Point-of-care HbA1c level is not at goal for this patient, who has high function, long life expectancy, few comorbidities, good support, health literacy, and access to care. Medical history is significant for hypertension, hyperlipidemia, and obesity. His family history is notable for type …

A 63-year-old man is evaluated for severe mid-upper back pain following a minor fall 1 day ago. He also notes progressive fatigue of 6 months’ duration and a 6.8-kg (15-lb) weight loss. Medical history is notable for an 80-pack-year smoking history, although he is currently a nonsmoker.
On physical examination, temperature is 37.3 …
In early November, Chuck Norris filed a lawsuit against medical device manufacturers involving gadolinium-based contrast media, a chemical used in MRI imaging scans. The lawsuit stated that the gadolinium that doctors injected into his wife Gena to improve the clarity of her MRIs have left her “weak and tired and with debilitating bouts of pain and a burning sensation.”
As with any adverse effects involving medical procedures in the news, it …
Patsy loved playing bingo every Wednesday night. Her boyfriend of three years loved watching her daughter Jenna who was a tiny and pretty six-year-old her momma called “princess.”
Even though they weren’t related, Jenna called Patsy’s boyfriend “Uncle Billy” at her mother’s behest.
And Uncle Billy made Jenna shyer and quieter than she usually was. He’d walk in on those Wednesday nights and demand a big hug and kiss on the cheek …
Triage Note: Fish hook in eye. No bleeding. Tetanus up to date.
It’s a sunny weekend during cottage season. A young woman is rushed into the ER as she cups both hands over her left eye. She’s in shorts, and flip-flops, and she’s hyperventilating. Her friends follow, hands similarly cupped over their mouths. I read the triage note. I’ve never seen this before. I’ve removed dozens of fish hooks — it’s …
How would you like to double your chances of winning the lottery? Just buy two tickets!
Statistically, this is true, but is that a reason to spend more money on something that most likely offers no return on investment?
Yet, in medical research, study after study shows impressive improvement in relative risk for this, that and the other intervention but a small or even negligible effect on absolute risk.
For example, I just …
Diverticulitis is a common and sometimes serious problem that affects several hundred thousand people each year. Diverticulitis is the condition where small outpouchings or “pockets” in the wall of the large intestine called diverticula become inflamed and infected, and typically presents as a constant lower abdominal pain, associated with fever or chills, and often bloating or constipation symptoms. Despite becoming even more common in recent years, not much is understood …
Part of a series.
Cognitive decline is a normal process of aging; Alzheimer’s is a disease.
Cognitive decline due to aging can be slowed but not halted with appropriate lifestyle approaches. The “big four” are equally important to slow cognitive decline: Don’t smoke. Reduce stress. Exercise often. And eat a quality diet in moderation.
Good sleep and brain stimulation need to be added for maintaining good cognition. Some form of …

A 32-year-old woman is evaluated for a 2-month history of weight loss, abdominal cramping, and loose stools. Her stools are malodorous, but she has not noted any blood associated with her bowel movements. Although her appetite is good, she has lost 3.2 kg (7.0 lb). She has an 8-year history of diffuse …

It seems that everyone has advice about sleep these days, and we have become immune to it. “Avoid naps, caffeine and alcohol close to bedtime. Get exercise. Get out of bed if you can’t sleep. Turn off the TV and any electronic devices hours before bedtime. Enjoy a relaxing ritual. Keep to a routine.”
Please do all of these, because they actually work! Shifting your bedtime later to achieve sleep consolidation …
Eighty percent of diagnoses can be made based on the history and physical. Take the subjective and objective; throw in some medical history, family history, social history and you can figure out your assessment and plan. Doctors are the detectives of the body and the more facts, the easier it is to solve the mystery.
This is the fictional note that I wrote in my head concerning a fellow physician friend …
I see these couples quite often: the man has been prescribed androgen deprivation therapy and his partner is distressed. He no longer has erections, although for some that had been a problem for years. But even then, they tell me, he at least tried occasionally. Now there is nothing. No hugs, no kisses, no hand holding, no touch. The partners are …
Dr. Tara Zandvliet was inundated with calls and emails from parents last year, after California passed a law nixing personal beliefs as an exemption from school vaccinations. Suddenly, many parents sought exemptions for medical reasons.
Someone even faked two medical exemption forms purportedly written by the San Diego pediatrician, copying a legitimate document she’d provided for a patient and writing in the names of students she’d never treated, she said. She …
A study published in JAMA looking at the brains of former football players donated to a brain bank, a highly selective sample, found signs of chronic traumatic encephalopathy (CTE) — a degenerative neurological disease — in nearly all deceased players examined.
The mainstream media converged towards numerical consensus.
I swiped this editorial cartoon by Steve Sack from the redoubtable Dr. David Gorski’s blog, who goes by the nom-de-web of Orac. Recent epidemiology shows reducing the fraction of vaccinated children in the population rather promptly leads to a resurgence of the diseases vaccines protect against. This is the concept of community or herd immunity.
Epidemiologists debate the concept around …
The Society to Improve Diagnosis in Medicine has on its website this quote:
The current focus on diagnostic error raises an interesting question: Is this a larger problem in 2017 than in the 1970s and 1980s?
